Description

Technical Field

[0001] The invention relates to the technical field of water quality suspended matter detection, and in particular to a water quality suspended matter detection auxiliary device. Background Art

[0002] Suspended matter in water refers to solid matter that is retained on the filter membrane after the water sample passes through a filter membrane with a pore size of 0.45 μm and is dried to a constant weight at 103-105°C. Existing suspended matter detection devices for water quality generally include a suction filter bottle, a vacuum pump, a funnel and a filter membrane. At present, when testing water quality, firstly, a sample is taken from the water source of the water area to be tested, then the filter membrane is placed in the filter membrane filter, then the filter membrane filter is sealed and connected to the bottle mouth of the suction filter bottle, and finally the suction filter bottle is connected to the vacuum pump, and the water sample to be tested is poured into the filter membrane filter for suction filtration.

[0003] The invention discloses a water suspended solids detection auxiliary device with the publication number CN115683809A, comprising: a shell; a support mechanism, the support mechanism is connected to the shell; a filter mechanism, the filter mechanism is arranged outside the support mechanism and is connected to the shell; wherein the filter mechanism comprises: a filter membrane pushing assembly, the filter membrane pushing assembly is connected to the shell; a water guiding assembly, the water guiding assembly is arranged outside the support assembly and is connected to the support mechanism; a support assembly, the support assembly is arranged between the support mechanism and the water guiding assembly and is connected to the filter membrane pushing assembly. By setting the filter mechanism, the support assembly cooperates with the water guiding assembly and the filter membrane pushing assembly, the automatic collection of water suspended solids can be realized. The replacement process of the body does not require manual operation, and the operation process is simpler; although the device can realize automatic collection of suspended solids in water, when collecting suspended solids in water, the device needs to first use the first motor to push the filter membrane into the filter membrane filter, and then move the filter membrane filter equipped with the filter membrane to the suction filter bottle, and then use the electric telescopic rod to drive the filter membrane filter to seal the bottle mouth of the suction filter bottle. The whole process will use multiple electrical components, which will not only increase the procurement cost, but also be unfavorable for subsequent maintenance. In addition, the device directly pushes the filter membrane into the filter membrane filter from one side, so when it is pushed to a semi-suspended state, the filter membrane is prone to tilt and cause jamming, and then manual intervention is required, which greatly affects the collection efficiency.

[0004] The publication number is CN118243579B. A water quality suspended matter detection device comprises a base, a sampling assembly and a suction filter mechanism are arranged on the top of the base, air bags are arranged at positions on both sides of the base, two fixing rings are fixedly mounted on the air bags, and the four fixing rings are fixedly connected to the bottom of the base, a propulsion assembly is arranged at the bottom of the base, and a camera and a signal transmission module are also arranged on the top of the base; the suction filter mechanism comprises a rotating shaft arranged to rotate along a plumb line, a plurality of connecting plates are evenly distributed on the peripheral wall of the rotating shaft along its circumference, the ends of the connecting plates are fixedly connected to a vertically arranged rotating tube, the lower port of the rotating tube is fitted with a connecting tube threadedly connected thereto, a drainage plate fixedly connected to the inner wall thereof is arranged in the lower port of the connecting tube, and a plurality of drainage holes are arranged through the top of the drainage plate; although the device can place the filter membrane in the membrane filter from above, the entire placement process requires the telescopic cylinder, the suction fan and the first motor to cooperate with each other, and the use of so many electrical components will not only increase the procurement cost, but also be unfavorable for subsequent maintenance.

By controlling the rotation of the membrane filter 8, the positions of the four membrane filters 8 can be changed, thereby facilitating continuous detection of water quality. The first motor 6 can be controlled by a program so that it can only rotate forward ninety degrees at a single start, so as to achieve precise adjustment of the position of the membrane filter 8. By setting the operating holes 50, when the membrane filter 8 rotates to the front and rear, the membrane inside the membrane filter 8 and the water suspended matter on the membrane can be easily removed.

[0037] like Figure 1-4 As shown, a pressing mechanism for tightly connecting the membrane filter 8 with the mouth of the suction filter bottle 2 is arranged near the left side inside the detection box 1, and a driving mechanism for driving the membrane adding mechanism and the pressing mechanism to operate synchronously is installed inside the detection box 1, and the driving mechanism includes a motor mounting plate 32 fixedly connected to the inside of the detection box 1, a second motor 33 is installed on the motor mounting plate 32, and a gear plate 34 is fixedly connected to the outer surface of the output end of the second motor 33, and a second rotating shaft 35 and a third rotating shaft 36 are rotatably installed on the inner bottom wall of the detection box 1, and the outer surfaces of the second rotating shaft 35 and the third rotating shaft 36 near the bottom are fixedly connected with synchronous The second gear 37 is fixedly connected to the outer surface of the second rotating shaft 35 near the top, and the second gear 37 is meshed with the toothed disc 34.

The second rotating shaft 35 and the third rotating shaft 36 are both rotatably connected to the second support plate 40. The second motor 33 is started, and the second motor 33 can drive the toothed disc 34 to rotate.

The distance between the storage cylinder 13 and the rotating cylinder 20 is less than the diameter length of the filter membrane. By opening a notch on the second movable plate 18, the second movable plate 18 can avoid interference with the first square column 14 when the first movable plate 15 and the second movable plate 18 move synchronously. After driving the right-angle seat 16 to move to the maximum extent in the direction of the storage cylinder 13, the circular opening opened by the right-angle seat 16 will be concentric with the storage cylinder 13. At this time, the filter membrane at the lower left inside the storage cylinder 13 will fall into the circular opening. After driving the right-angle seat 16 to move to the maximum extent in the direction of the rotating cylinder 20, the circular opening opened by the right-angle seat 16 will be concentric with the rotating cylinder 20. At this time, the continued movement of the first movable plate 15 will drive the second movable plate 18 to move accordingly and lengthen the second spring 19.

[0040] like Figure 3 and Fig. 9 As shown, the bottom surface of the first movable plate 15 is fixedly connected with the second tooth plate 31, and the second tooth plate 31 is meshed with the third gear 39. The rotation of the third gear 39 can drive the second tooth plate 31 to move horizontally, and the movement of the second tooth plate 31 can drive the first movable plate 15 to move accordingly.

[0041] like Figure 2 , Figure 3 , Figure 4 ,, Fig. 9 and Fig.10As shown, the bottom of the rotating cylinder 20 is provided with two symmetrical semicircular baffles 21, and the back of the rotating cylinder 20 is provided with a limiting assembly for limiting the two semicircular baffles 21. The limiting assembly includes a second square column 28 fixedly connected to the top wall of the detection box 1, and a guide column 27 is fixedly connected between the two second square columns 28. The outer surface of the guide column 27 is slidably connected to the first right-angle connecting rod 24 and the second right-angle connecting rod 25. The first right-angle connecting rod 24 and the second right-angle connecting rod 25 are fixedly connected to the sides away from each other. A third spring 29 is connected, and the ends of the two third springs 29 that are away from each other are fixedly connected to the two second square columns 28 respectively. The first right-angle connecting rod 24 is fixedly connected to one of the semicircular baffles 21, and the second right-angle connecting rod 25 is fixedly connected to the other semicircular baffle 21. The first right-angle connecting rod 24 and the second right-angle connecting rod 25 are fixedly connected to the first toothed plate 26 on one side close to the middle rotating cylinder 20. The back of the middle rotating cylinder 20 is rotatably installed with a first rotating shaft 22, and the outer surface of the first rotating shaft 22 is fixedly connected to a first gear 23, and the first gear 23 is meshed with the two first tooth plates 26. The back of the first movable plate 15 is fixedly connected with a right-angle push rod 30 for pushing the upper first tooth plate 26. After the right-angle seat 16 moves to the maximum extent in the direction of the middle rotating cylinder 20, the right-angle push rod 30 will move to contact with the first tooth plate 26. At this time, the first movable plate 15 continues to move to drive the right-angle push rod 30 to push the upper first tooth plate 26 to move to the left. The upper first tooth plate 26 moves to the left to drive the first gear 23 to rotate accordingly, and the first The rotation of the gear 23 can drive the first tooth plate 26 below to move to the right, so that the two semicircular baffles 21 can move away from each other to leak out of the opening at the bottom of the rotating cylinder 20, and then the filter membrane can fall from the rotating cylinder 20 to the interior of the membrane filter 8 below. The movement of the two first tooth plates 26 can respectively drive the two third springs 29 to be compressed to a certain amount, so that when the first moving plate 15 and the right-angle push rod 30 are reset, the third spring 29 can drive the first tooth plate 26 and the semicircular baffle 21 to reset.

[0042] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, the pressing mechanism includes a support seat 42 fixedly connected to the inner bottom wall of the detection box 1, a cylinder 46 is fixedly connected to the upper surface of the support seat 42, a fourth spring 48 is fixedly connected to the inner bottom wall of the cylinder 46, a round rod 47 is fixedly connected to the other end of the fourth spring 48, and the round rod 47 is slidably connected to the cylinder 46, an end of the round rod 47 away from the fourth spring 48 is fixedly connected to an arc seat 41, a track groove is provided inside the arc seat 41, an arc inclined plate 49 is fixedly connected inside the track groove, a pressing rod 12 is fixedly connected to the bottom surface of the toothed disc 34, and the pressing rod 12 is slidably connected to the track groove, The end of the pressure rod 12 away from the toothed disc 34 is in contact with the arc-shaped inclined plate 49. When the toothed disc 34 is driven to rotate, the pressure rod 12 can be synchronously driven to slide along the track groove. Due to the existence of the arc-shaped inclined plate 49, when the toothed disc 34 rotates forward, the arc-shaped inclined plate 49 and the arc-shaped seat 41 will be gradually squeezed to move downward. The downward movement of the arc-shaped seat 41 can drive the round rod 47 to slide downward along the cylinder 46 and compress the fourth spring 48. When the toothed disc 34 rotates reversely, the fourth spring 48 will push the arc-shaped seat 41 and the arc-shaped inclined plate 49 to move upward, so that the arc-shaped inclined plate 49 is always in contact with the pressure rod 12.

[0043] like Figure 1 , Figure 5 and Figure 6 As shown, the outer surface of the arc seat 41 is fixedly connected to the first right-angle plate 43, the upper surface of the first right-angle plate 43 is fixedly connected to the second right-angle plate 44, the outer surface of the second right-angle plate 44 is fixedly connected to the pressure ring 45, the pressure ring 45 is located between the funnel 4 and the membrane filter 8 and is concentric with the funnel 4, and a sealing ring 11 is installed at the bottom of each membrane filter 8. The movement of the arc seat 41 can drive the second right-angle plate 44 and the pressure ring 45 to move accordingly. When the pressure ring 45 moves downward, it can drive the membrane filter 8 and the sealing ring 11 below to move downward and compress the first spring 10. After the sealing ring 11 moves to contact the bottle mouth of the vacuum pump 3, the membrane filter 8 continues to move downward to squeeze the sealing ring 11, thereby realizing a sealed connection between the membrane filter 8 and the bottle mouth of the vacuum pump 3.

[0044] Working principle: After the device is assembled, the membrane filter 8 on the right is concentric with the rotating cylinder 20, the membrane filter 8 on the left is concentric with the suction filter bottle 2, and the membrane filters 8 at the front and rear are concentric with the two operating holes 50 respectively. After the device is moved to the specified position, the second motor 33 is controlled to rotate in the forward direction, and the second motor 33 can drive the toothed disc 34 to rotate. The rotation of the toothed disc 34 can drive the second gear 37, the second rotating shaft 35 and the third gear 39 to rotate synchronously. The rotation of the third gear 39 can drive the second toothed plate 31 to move horizontally in the direction of the rotating cylinder 20. The movement of the second toothed plate 31 can drive the first movable plate 15, the right-angle push rod 30, the right-angle seat 16 and the compression assembly to move accordingly. When the right-angle seat 16 moves to the maximum extent in the direction of the rotating cylinder 20, the circular opening opened by the right-angle seat 16 will be concentric with the rotating cylinder 20, and the right-angle push rod 30 will move to contact with the first toothed plate 26. At this time, the first movable plate 15 continues to move to drive the second movable plate The movement of the first gear 23 can drive the first gear 23 to rotate accordingly. The rotation of the first gear 23 can drive the first gear plate 26 below to move to the right side, so that the two semicircular baffles 21 can move in the direction away from each other to leak out of the opening at the bottom of the rotating drum 20, and then the filter membrane can fall from the rotating drum 20 to the inside of the filter membrane filter 8 below. The movement of the two first gear plates 26 can respectively drive the two third springs 29 to be compressed to a certain amount. After the filter membrane falls into the inside of the filter membrane filter 8 below, the second motor 33 is controlled to rotate in the opposite direction, so that the first movable plate 15 and the right-angle push rod 30 can be reset. During the resetting process of the first movable plate 15 and the right-angle push rod 30, the third spring 29 can drive the first gear plate 26 and the semicircular baffle 21 to reset.

[0045] After the filter membrane is added to the membrane filter 8, the first motor 6 is started. The first motor 6 can drive the cross seat 7 and the four membrane filters 8 to rotate ninety degrees, and then the above steps can be repeated to add the filter membrane to the next membrane filter 8. When the first membrane filter 8 with the filter membrane added is controlled to rotate to the same center as the suction filter bottle 2, the gear disc 34 can synchronously drive the pressure rod 12 to slide along the track groove while rotating. Due to the presence of the arc-shaped inclined plate 49, when the gear disc 34 rotates forward, it will gradually squeeze the arc-shaped inclined plate 49 and the arc-shaped seat 41 to move downward. The downward movement of the arc-shaped seat 41 can drive the round rod 47 to slide downward along the cylinder 46 and compress the fourth spring 48. The movement of the arc-shaped seat 41 can drive the second right-angle plate 44 and the pressure ring 45 to move accordingly, and the downward movement of the pressure ring 45 can drive the filter membrane below to pass The filter 8 and the sealing ring 11 move downward and compress the first spring 10. When the sealing ring 11 moves to contact the bottle mouth of the vacuum pump 3, the membrane filter 8 continues to move downward to squeeze the sealing ring 11, thereby realizing a sealed connection between the membrane filter 8 and the bottle mouth of the vacuum pump 3. After that, the water pump 5 and the vacuum pump 3 are started, so that the water sample can pass through the pressure ring 45, the filter membrane and the membrane filter 8 in turn and fall into the interior of the suction filter bottle 2, and the water suspended matter will remain on the filter membrane, thereby realizing automatic collection of the water suspended matter. Then, when the second motor 33 is controlled to rotate in the opposite direction, under the action of the fourth spring 48, the arc seat 41 will be reset together with the first moving plate 15, etc., and when the membrane filter 8 containing the filter membrane rotates to the front and rear, the filter membrane inside the membrane filter 8 and the water suspended matter on the filter membrane can be taken out from the operating hole 50.
